Filed: 1945-10-23
Abstract: 631,658. Sterilizing liquids. DENIER, A Oct. 23, 1945, No. 27936. Convention date Oct. 23, 1944. [A Specification was laid oper to inspection under Sect. 91 of the Acts April 24, 1946.] [Class 49] [Also in Group XXXVI] In a method of sterilizing or de-acidifying alimentary liquids, for example, fruit juices and milk, the liquid is passed into a container where its speed is reduced before it overflows in the form of a thin sheet, and thereafter is electrolyzed as it passes in a thin layer between electrodes. In the arrangement shown, the liquid enters a container 100 through an opening 103 and overflows into an annular vat 102, in which is immersed a ring-shaped electrode 107. This electrode is made of aluminium if the liquid is to be de-acidified, and is made of aluminium and silver if the liquid is to be de-acidified and sterilized. The container is connected in an electric circuit as cathode and the electrode 107 as anode.

IPC: B21B1/22
Filed: 1948-10-28
Abstract: 655,444. Angular bending; stretching. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 28, 1948, No. 28017. [Class 83 (iv)] Sheet or strip is reduced in thickness by subjecting it to a tension slightly less than that at which it would stretch plastically and subjecting it to a bending stress. Coiler drums 6, 7 rotated by reversible electro motors 8, 9 through reduction gears 10, 11 apply tension to the strip 24 at values less than those which would cause plastic deformation. It passes under rolls 16, 17 and over a small diameter lubricated roll 18 which applies a bending stress which causes plastic deformation and reduction of the thickness of the strip localised on the portion of the strip passing over the roll. In a modification, Fig. 5 (not shown), the strip is passed round a plurality of small diameter rolls immersed in lubricant.

Title: Method of manufacturing deep drawing blanks and apparatus for carrying out this method
IPC: B29C51/14
Filed: 1972-06-15
Abstract: 1385529 Stamping CEBAL GP 15 June 1972 [16 June 1971] 28114/72 Heading B3Q [Also in Division B5] Laminated deep-drawing blanks are made by adhering a metal foil to a thermoplastic foil at least temporarily and only in localized regions constituting the blanks, cutting the blanks from the localized regions and recovering the waste part of the foils. A preferred laminate is made from a plastics-metal-plastics assembly. Temporary adhesion is effected by heating the thermoplastic foil(s) to the fusion point and pressing all the foils together, and is made permanent by means of adhesive or by treatment with X-rays. Adhesion may be effected over part only of the area constituting the blank. The laminated material may be prepared by heating the thermoplastic foils in a high-frequency oven and maintaining them at the required temperature, sandwiching a metal foil therebetween by means of pressure rollers, deepdrawing and/or cutting out the bonded portions and removing the unbonded waste material on to separate rollers. The plastics material may be polypropylene, polyethylene, polyvinyl chloride, polyamide or polyimide and may be fused at 145-300 C.; it may be reinforced. The metal may be aluminium, tin, zinc or an alloy thereof. The deep-drawn product may be used in the manufacture of packaging material. Fig. 3 shows a deep-drawing tool in which a punch 211 and a blank-holder 213 operate on a circular bonded zone 1111-1131 and a cold peripheral zone 1114-1134 (which prevents softened material from leaking outside the apparatus), respectively, in conjunction with a sealing ring 2111, a die 212 and a base 214. If the blank is bonded only in regions subjected to maximum stress during deep-drawing, i.e. the folded portions, the base and sealing ring may be dispensed with. Fig. 4 (not shown) illustrates a blank which is bonded over three concentric annular portions and certain connecting regions.

Title: Improvements in optical scale-reading apparatus
Filed: 1936-09-24
Abstract: 482,262. Optical scale-reading apparatus. KAPELLA, Ltd., and REASON, R. E. Sept. 24, 1936, No. 28845/37. Divided out of 482,202. [Class 97 (i)] Apparatus for reading a divided scale comprises an optical system for forming at least one of two juxtaposed representations of the scale which are of different pitch and move in opposite directions relatively to the optical system when the scale reading changes, so that the two representations can be viewed simultaneously and one serves as a vernier for reading in conjunction with the other. In the form shown in Fig. 3, particularly intended for reading a straight scale, a transparent support A<1> carried by a body whose movements relatively to a fixed base are to be measured bears two scales A, B of different pitches. An inverted image b of the scale B is formed alongside the scale A by a concave reflector F<1>, the scale B being illuminated by rays from a lamp F<2> reflected by a mirror F<3> and passing through a lens F<4>. The scale A and image b are viewed through a microscope or eyepiece E. A separate digit scale may be marked on the support A<1> so that it is seen in the eyepiece ; the scale A and image b then act together as a vernier to give the fractional reading, the approximate reading being obtained from the digit scale. Figs. 5 and 6 show a form, also intended especially for reading a straight scale, in which two images, one inverted and one erect, of a single scale A are observed. The rays forming the two images are separated by an apertured mask G<2> in the focal plane of a field lens G<1>. The images are formed by objectives H, H<1> the scale lying in the focal plane of the objective H so that the rays are parallel between the objectives. A biprism H2 and field lens H3 are disposed in the image plane to form superposed images of the mask apertures G3, G<4>. The rays traversing the aperture G<3> pass through a reversing prism J to invert one image in a direction parallel to the length of the scale, and the rays traversing the aperture G<4> pass through a telescope K which produces a slightly magnified image. The support A<1> may also carry a digit scale D which is imaged by the part of the system forming the larger image. In a modification the support A<1> carries two scales of slightly different pitches, one being imaged by rays passing through the aperture G3 and the other by rays passing through the aperture G4, the telescope K being dispensed with. Fig. 8 shows one form for use with a circular scale. Scales A, B of different pitches are marked on a transparent angularly-movable disc L in diametrically opposite positions at equal radii and are obliquely projected by similar lenses M<2> carried by a fixed part M to form juxtaposed images near the axis of rotation of the disc. The rays are deflected parallel to the axis by reflectors M<3> and are observed through an eyepiece M<4>. A digit scale D is provided adjacent the scale A.
